block

问题 I have this basic example that should display these three table cells as blocks (underneath each other) on mobile devices. Yet this doesn't seem to work out on iPad, iPhone, nor on a Samsung phone. It does work on regular browsers and websites that simulate a mobile display (for web pages probably), but when viewing on actual mail clients of mobile devices, the display: block property seems to be ignored. Is there anything that's missing? Or if the display -attribute isn't supported at all,

问题 I am new to Wordpress Gutenberg blocks. I created a gallery plugin and I want a user to be able to insert gallery shortcode by simply choosing the desired gallery from a popup window. I use jQuery text() function to inject shortcodes from the popup window with success but the content will not be saved. However, when I type in some text everything works fine. Here is my Gutenberg js: var el = wp.element.createElement, registerBlockType = wp.blocks.registerBlockType, RichText = wp.editor

问题 Trying to write a Ruby code that will count unique words and return their total occurrences. So suppose I want to find number of occurrences for Sally, Marina and Tina in the following sentence "Monday Tina will meet Sally and Harris. Then Tina will visit her mom Marina. Marina and Tina will meet David for dinner." I tried the following but this defeats the dry principal. Is there a better way? string = "Monday Tina will meet Sally and Harris. Then Tina will visit her mom Marina. Marina and

问题 I have an array of PFFiles I retrieve from parse. The PFFiles must be converted to images and I am trying to convert them in a loop, however; The array of converted images must be in the same order of the array containing the PFFiles . The problem is, is the loop runs and causes all of the blocks to trigger, then they are all loading at the same time thus the imageArray will result in a different order to the original array of PFFiles , because if one object finishes loading before the

问题 I am concerned about writing self-modifying code in Ruby. And by self-modifying, I mean being able to write functions that take a code block as an input value, and output another code block based on this. (I am not asking about basics such as redefining methods at runtime.) What I might want to do is, for example, having the following block, _x_ = lambda { |a, b, c, d| b + c } one can notice that arguments a and d are not used in the body at all, so I would like a function eg. #strip to

问题 The details here aren't important, it's just an example, all that matters is the i=0, i+=1 action def sortAndIndex #sorting keys @disco = Hash[@disco.sort] #basic setup for both input types @years = @disco.keys @albums = @disco.values sum = @years.count #setup for "albums" input @allalbums = [] i = 0 sum.times do thatyear = @years[i] + ", " + @albums[i] @allalbums << thatyear i += 1 end end Now this does work, as should any other "i++" type ("C-style") iterator in ruby or most other languages

问题 I'm implementing network layer of my application, that is using an asynchronous JSON-RPC protocol. In order to communicate with the server, i'd like to make a method that will send a proper request, wait until the server sends response, and return it. Everything with use of async/await keywords. Here's simplified sample code: string response; Task<string> SendRequest(string methodName, string methodParams) { string request = generateRequest(methodName, methodParams); await Send(request); //

问题 I'm reading a Ruby book but it doesn't explain the following: What is this: validates :name, :presence => true I mean I know what it does but what's validates ? Is it a method of the validator class? If so, how come it's called without mentioning the class name first? What's the meaning of : in the previous code and in Rails on general? In the following code: <%= form_for([@post, @post.comments.build]) do |f| %> Is form_for an object or a procedural function? What's the meaning of the |

问题 I have a template in app\design\frontend\base\default\template\dir\template.phtml that look like this <div class='block block-list'> <div class='block-title'><strong><span>Some Block</span></strong></div> <div class='block-content'>  <?php echo "my content"; ?> </div> </div> I positioned the block on the catalog page by adding the following code to the local.xml file. However is it possible to position the block to the top of the column at the same time? <?xml version="1.0"?> <layout version=
